【摘要】 在榉木、云南红豆、紫檀3个珍贵树种的盆苗培育期,施用Cu、Zn、Mn、B、Mo 5种元素组合的微肥促进其苗木高、径生长的试验结果表明,在其40周的育苗期内,适量施用此5种元素组成的微肥对此3个珍贵树种盆苗苗高和地径的生长均有极显著的促进作用,其苗高增幅达32.2%~62.4%,地径增幅达26.3%~66.4%;极差分析表明,在3个珍贵树种的盆苗培育期所施用的微肥中对各个树种苗木的高径生长起有促进作用的5种微量元素均有最佳的用量组合。更多还原

【Abstract】 Potting experiments were conducted to study the responses of seedlings of three precious and rare tree species named Zelkova scheideriana,Pterocarpus indicus and Ormosia yunnanensis to micronutrient including Cu,Zn,Mn,B and Mo.The experimental results showed that during the seedling raising period of 40 weeks,application of the tested micronutrients had significant function on the growth of both height and diameter,the seedling height and diameter increased by 32.2 % ~ 62.4 % and 26.3 % ~ 66.4 % respectively.The optimum content combination for the growth of height and diameter of the seedlings of each tested tree species were obtained by range analysis.更多还原
